Abstract

REYES-AMAYA, Nicolás; LOZANO-FLOREZ, Julián; FLORES, David  and  SOLARI, Sergio. Distribution of the spix’s disk-winged bat, Thyroptera tricolor SPIX, 1823 (Chiroptera: Thyropteridae) in Colombia, with first records for the middle Magdalena Valley. Mastozool. neotrop. [online]. 2016, vol.23, n.1, pp.127-137. ISSN 0327-9383.

Thyroptera tricolor is a rarely collected bat species that inhabits lowland forests in Central and South America. We review the distribution of T. tricolor in Colombia, using previous and new records deposited in scientific collections of the world, providing a distribution map and a gazetteer with comments on available geographical information. We also provide first records for the Middle Magdalena Valley, with external and cranial measurements. These new records reduce the distributional gap between northern and southern records of the country. Additionally, by comparing dental measurements of our recent specimens with fossil records of thyropterids from the Magdalena Valley (La Venta deposits), we contribute to understanding the evolution and distribution of this group, reinforcing the hypothesis of evolutionary stasis.
